网络层次分析法在桥梁工程招标中的应用

简述了公路桥梁建设中的招标程序，比较了最低标价法和综合评价法的优缺点，介绍了一种新的评标方法——网络层次分析法ANP(analytic network process)。在综合考虑各种因素的同时，考虑到因素间的相互影响，对各因素以1～9为标度进行量化，两两比较，最后进行综合排序。利用超级决策SD(super decisions)软件计算了一个实例。计算结果表明，ANP是一种科学的实用评标方法。

Application of analytic network process to evaluation oftender bids for bridge engineering

Tendering procedure in highway bridge construction was stated. Both advantages and disadvantages of the method of the lowest bidding price were compared with the synthesizing evaluation method. A new evaluation method known as the analytic network process (ANP) was introduced. ANP considered all factors, estimated the relative influence from the factors, values factors with ratio scales from 1 to 9, made pairwise comparisons on factors and synthesized to get overall results. An ANP case was conveniently computed by super decisions ANP Software. The computed result shows that ANP is a more scientific evaluating method.
